The 618 in my wife's plane just stopped receiving signals. (the SNR
screen reads all '0's). Checked continuity to the antenna and it's OK.
Is it possible that those antennas could just quit? If the 618 itself
quit its not worth fixing, but it had always made a good backup.

That antenna is active (has an amplifier built into the base), so yeah...
it could do that. It's also possible that you broke a wire in the antenna
portion itself (the vertical - it's really a coil), or a connector came
loose, or even the front end of the receiver itself.

I do have a replacement amplifier (base of the antenna, but not the
vertical - which, I seem to recall, simply screws in), See if you can
narrow it down to that (vs. something else) and give me a holler if it
really is the amp.
